'lO ALL WI'IOM IT MAY CONCERN:

Bo it known that I, JOHNO. DELAVIGNE, of New Orleans, in the parish ofOrleans, and State of-Louisiana, have invented a new and usefulImprovement in Stam-Plough; and I do'hereby declare that the. followingis n. full, clear, and exact description thereof, which will enablethoseskilled in the art to make and use the same, reference being had to theaccompanyingdrawings, forming part of this specification.

This invention relates to a new and improved method of ploughing andcultivating land by steam-power, and the invention consists in providingfenders for the protection of growing plants, and in theombinationandarrangement of parts, as will he herein described. l v

Figure 1 represents a sectional side elevation ofthe machine, thesection being through the line :c :v of iig. 2..

Figure 2 is a top or plan view of the same.

vFigure 3 is a detached sectional view of the main shaft or axle. l

`Figures 1 and 5 are detailed views of the gang-ploughs and cultivatorsused, showing the form and modifications of the same.

Similar letters of reference indicate corresponding parts.

represents the platform which supports the steam-engine, and to whichthe `ploughs are attached. B represents the traction-wheels, which arelarge in diameter, and with broad tires. C is the steam-engine, whichisof the portable kind; or with theiengine and boiler attached together. Drepresents the gangs of ploughs or' cultivntors, which are attached toand operated by the machine. E represents groups of vertical rods, whichare placed between the gangs of. ploughs,lfor`the purpose of preventingthe young plants from being coveredl by the plonghs. F represents aguide or steering-wheel, attached .to the forward part of the machine.This wheel is operated by the lever g, and fastened in any desiredpositi'on by pins through the traverse-bar t, as seen in the drawing.The motion and power of the engine are first imparted to the gear-wheela, by means of n. pulley, u', on the other end of this wheel-shaft-b.From this wheel a there is a continuation of gearing down 4 to the nininshaft II, to which the traction-wheels B are attached, as seen infig. 1. The main shaft is in three parts. thus allowing the wheels B tomove independently of each other, when desired. This arrangement is seenin iig. 3. The parts of the shaft may be described as c, d, and e. Thepart d i; attached to the frame by box-journals jlf. The parts c and eare also attached to the frame by journals, one of which for each partis seen in the figure, marked To their outer ends, the wheels B areattached. The parts of the shaft are 4 coupled together`4 bysleeve-couplings, seen at J J, which are operated by levers, marked K.The shaft and sleeve-coupling muy besquare in its cross-section, andvthe sleeve slipped over the ends of the parts, asseen in the drawing,or they may be round, and the coupling made to slide on a fin or featherin the parts of theV shaft. These shiftinglevers are always at thecommand of the attendant, so that the shaft may'be separatedn whennecessary, in turning, tc. In reducing the motion from the speed givenby the engine'to the gear-wheel a and 4pulley a', 'and shaft b, to themotion desired for the main shaft H, the power will be increased inproportion to such reduction. The speed of the engine would be, perhaps,one hundred or one hundred and fifty strokes per minute, while themachine would move over the ground with only about the speed of awalking horse. The groups oi' rods E extend down from the frame to theground, as seen in fig. 1, for the protection of the young piants. Afterthe plants obtain a. suiiiciently large growth, and also iu breaking upland, they may bc removed, as they are attached to blocks m, 1,) 'whichare bolted to the frame.V i

The form of plough used in this machine may be varied according to thesoil in which it is used, consequentlyI do not confine myself to anyparticular form, or size, or number, either of the ploughs orcultivators, to be used at one time. f

The gangs of ploughs and cnltivators are attached to the frame by rods,chains, or ropes, which are marked N, while the depth which the ploughsare allowed to cut is ,governed by other chains or ropes, marked o,which are attached to frame I). This frame is supported on an uprighttransverse frame, marked R, and to which it is attached by hinges at itsmiddle, soAtha't it can oscillate or rock. S is a wi'ndlass on the frameR, the shaft or drum of which extends across the machine, as seen in g.2, at T. o represents ropes or chains, which are attached to the frame Pand to thc windlass, as seen in the drawing. `The wiudlass is revolvedby a crank, u, and it is held .in place by a ratchet-wheel and pawl, v,as seen yin figl.

In breaking up the soil, it may be necessary to pass over the groundmore than once, to plough up the.

space between the wheels. In cultivating', the whole space may befinished at one passage of the machine. In both cases tlle wheels willrun on thesauie track, which track is not to be disturbed by the plough,but left always firm. This is an essential diference between mysteam-plough and any one heretofore made. v

By using the ordinary portable steam-engine for my plough, it will beseen that the engine can readily be applied to other purposes, assawing, grinding, driving ootton-gins, lso.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- 1. The construction -and arrangement of the frame A,of any desired size, in combination with the tractionwheels B,substantially as shown sindv described. i

2. In combination with the frame andwheels, the shaft H, formedsubstantially as described.

3. The arrangement and operationof the gangs of ploughs or cultivatorsD, and the manner in which-the same are controlled, substantiallyy asdescribed.

4. The vertical protecting-rods E, substantiallyas and for the purposesherein described.
